Pneumoconiosis is a systemic disease that is caused by long-term inhalation of productive dust during occupational activities and retention in the lungs, which is mainly caused by the diffuse fibrosis of the lung tissue. So how much dust in the living environment is harmful to us ?
1. An adult needs about 19m3 of air per day in order to obtain the required oxygen from it. If the air at the worker’s workplace contains a lot of dust, people working in this environment will inhale more dust into the lungs. When it reaches a certain amount, it can cause fibrotic lesions in the lung tissue and gradually make the lung tissue Hardening, loss of normal respiratory function, and occurrence of pneumoconiosis;
2. The dust in the air will also reduce the visibility of the atmosphere, promote the formation of smog, and affect the transmission of solar radiation energy;
3. Certain hard dust can damage the cornea and conjunctiva, causing corneal opacity and conjunctivitis;
4. Dust discharged into the atmosphere will cause atmospheric pollution. Many harmful gases, liquids or some metal elements can be adsorbed on them, and they will be carried into the lungs or adhered to the walls of the bronchial tubes with human breathing. , Causing or aggravating various diseases of the respiratory organs;
5. Dust in the workshop can also reduce visibility, affect vision, hinder operation, reduce labor productivity, and even cause accidents;
6. After the soluble toxic dust enters the respiratory tract, it can be quickly absorbed into the bloodstream, causing poisoning;
7. Radioactive dust can cause radiation damage;
8. The dust in the air falling on the rotating parts of the machine will accelerate the wear of the rotating parts and reduce the accuracy and life of the machine;
9. When dust blocks sebaceous glands and mechanically stimulates the skin, it can cause acne, folliculitis, pyoderma and chapped skin;
10. Dust enters the external auditory canal and mixes with sebum, which can form earwax;
11. What dust affects the body is respiratory system damage, including upper respiratory tract inflammation, pneumonia (such as manganese dust), lung granuloma (such as beryllium dust), lung cancer (such as asbestos dust, arsenic dust), pneumoconiosis (such as silica, etc.) Dust) and other occupational lung diseases.
